An Idaho biology teacher has learned the hard way that you can’t go around saying “vagina” all willy-nilly, especially when you’re teaching 10th graders in a biology class about anatomy.

Wait, what?

Tim McDaniel, who has been a biology teacher for 18 years, is under investigation after four parents were offended that he used the word “vagina” while teaching their teenagers about human anatomy.

“I teach straight out of the textbook, I don’t include anything that the textbook doesn’t mention,” says McDaniel. “But I give every student the option not to attend this class when I teach on the reproductive system if they don’t feel comfortable with the material.”

The complaining parents apparently missed the memo that in order to teach young people about the reproductive system, you have to say the actual words and not cute euphemisms like “lady flower” or “vay jay jay” or whatever uptight parents are calling it nowadays.

But it gets worse. It turns out that some parents aren’t just upset about his utterances of the dreaded V-word – they’re also in a panic over his other “blasphemous” teachings, which includes some classes about global warming (the horror!). Students from Dietrich School, where McDaniel teaches, are in an uproar over the investigation and have started a Facebook page called Save the Science Teacher.

Dietrich Superintendent Neil Hollingshead doesn’t think McDaniel will get fired, but a letter of reprimand may be kept in his file.
